"Control room" extension loudspeaker, Murphy B40.
I've been trying to find out what the remote loudspeaker that would have been fitted as part of a ships control system looks like. To be fitted as an external speaker to a B40, Plenty of photos of ships radio rooms, havn't been able to find any of where the loudspeakers would have been fitted.
Any ideas please? I suspect it will have a 600 ohm matching transformer nearby or in its cabinet.
